Start by simplifying all complex terms (anything term that can be broken down into an easier thing to work with). 4^2 is equal to 4x4 or 16, and the square root of 25 is 5. Now we have an expression that looks like this:

16-25x2

Using PEMDAS, we continue simplifying by multiplying 5 and two together, and then subtracting this from 16.

16-5x2
16-10
6

The value of this expression is 6.

4 squared = 16
Square root of 25 = 5
Equation = 16-5x2
Do 5x2 first because of order of operations
16-10 = 6

Given: △FKL, FK= a m∠F=45°, m∠L=30° Find: FL

mr Goodwill [35]

The sum of angles of a triangle is 180°, so m∠K = 180° -45° -30° = 105°.

The Law of Sines tells you

... FL/sin(∠K) = FK/sin(∠L)

Solving for FL, we get

... FL = FK·sin(∠K)/sin(∠L)

... FL = a·sin(105°)/sin(30°) = a·sin(105°)/(1/2)

... FL = 2a·sin(105°) ≈ 1.93185a

Compared to last year, the population of boom town has increased by 25%. The population is now 6,600. What was the population la

prisoha [69]

Answer:

5280people

Step-by-step explanation:

Given parameters:

Percentage increase of population = 25%

Population now = 6600

Unknown:

Population last year = ?

Solution:

Let the population last year = y;

Then;

Percentage of last years population plus the population of last year should give us this year's population;

( $\frac{25}{100}$ of y) + y = 6600

0.25y + y = 6600

1.25y = 6600

y = $\frac{6600}{1.25}$ = 5280people

Last year, there was 5280people in the locality.
